It removes some of the minerals and other important components of the salt water and not just the "junk."
Many people use them ( including me) without adding any extra trace minerals.
The problem is avoided by doing regular water changes.
A protein skimmer uses small bubbles to trap proteins. The bubbles then form foam at the top of the water which can then be removed make the resulting water clean.
A Protein skimmer is a device that take out protein from the water. Meaning, it takes out desolved solid wastes. The ocean has it's own protein skimmer built in: waves hitting the beach. In some more polluted areas you can literally see all the bubbles along the shore or beach. For a reef tank you must have one. For just a fish tank, it is highly recommended to have one.
If you ingest too much protein you can get protein poisoning, which is where your body isn't getting enough fat. I am not aware of any other disadvantages.
Did you use some medication in the tank? that can often color the skimmate.
Protein skimmers to remove small amounts of water. They create bubbles and this becomes the skimmate. Also, some water remains in the skimmer when it is on. In general people do not have to adjust their water or salinity because of skimmers. It is important to match the size of the tank and the skimmer.
Some advantages of protein powder are muscle building and weight loss. Disadvantages of protein powder usage are kidney stones, gout, and weight gain.
A skimmer weir is the plastic flap and the opening of the skimmer. It traps leaves that are pulled into the skimmer when the pump is running and then holds the leaves in the skimmer whne the pump shuts down
As long as your tank is established and is full of live rock and sand, there should be no spike. You rely mostly on rock and sand for filtering. Skimmer adds aeration and removes gunk but that gunk would hopefully be broken down safely by your rock if it wasn't for the skimmer. Skimmers are great for aerating water and removing proteins, keep it in if you can.
if your talking about the plane skimmer there is no skimmer but there is a very simulair plane called a dodo
A protein skimmer is not necessary unless you have a heavy bio load. It is used mainly when people have a packed reef tank, a large predator fowlr tank, or if you have fish and coral that require next to perfect water quality. It is recommended to have a skimmer however because it keeps your water quality better, your fish and coral happier, and it allows you to do less maintenance on the aquarium.
Purple Skimmer was created in 1922.
Widow Skimmer was created in 1839.
